SPECIFICATION forming part of Letters Patent No. 773,848, dated November1, 1904.

Application filed May 21, 1902.

T0 all whom, 7125 77u01/ concern:

Be it known that I, BYRON A. BROOKS, a citi- Zenv of the United States,and a resident of the borough of Brooklyn, city of New York, in thecounty of Kings and State of New York, have invented certain new anduseful Improvements in Type -Vriting Machines, of which the following isa specification.

Myinvention relates to type-writing machines, and more particularly totabulating, automatic line-spacing, line-lock, pressureroller release,carriage-return, and scale and pointer mechanisms.

The object of my invention is to provide eiiicient mechanisms of thecharacters pointed out and to render the Imachine as a whole moreeflicient.

y A further object of my invention is to provide a machine wherein oneof said mechanisms may contribute to, be utilized for, or facilitate theactuation of another or other of such mechanisms.

To these and other ends, which willhereinafter appear, my inventionconsists in the novel construction, arrangement, and combination ofparts to be hereinfter described, and more particularly pointed out inthe appended claims.

In the accompanying drawings, wherein various parts have been omitted orbroken away to better illustrate other parts of the structure, andwherein like reference characters represent corresponding parts in thevarious views, Figure lis a plan view of the machine with parts brokenaway.

Fig. 12 is a detailperspective view of portions of the tabulating mechanism. Fig. 13 is adetail perspective view of a portion of the line-spaceregulating device.

While I have illustrated the various features of my present inventionapplied to a three-quarter or diagonal-strike visible type-Writingmachine, it should be understood that the invention or any one or moreof the separate features thereof may be applied to other characters oftype-writing machines'.

The frame 1 of the machine has key-levers 2, pivoted at 3 therein, andeach key-lever is provided with a linger-key 1 at its forward end, thekey-levers being guided in their movement by a comb 5 near the forwardends thereof, which comb is secured to a crossbar 6, attached to theframe. Each key-lever has pivoted thereto a't7 an upwardly-extendinglink 8, the upper end of each link being' pivoted at 9 to an arm 10,that projects from a segmental actuating part 11, that is pivoted at 12and is provided with gear-teeth 13 on the segmental edge thereof. Theseteeth 13 mesh with teeth 14 on a segmentalportion 15, connected to orforming the heel of a typebar 16, that may be provided with an internalraceway for cooperation with antifrictionballs 17, interposed betweenthe raceway of each type-bar and a support extending from the type-barhanger 18, and a depending portion 18 of each hanger constitutes asupport to which the associated part 11 is pivoted. The various type-barhangers may be secured by screws 19 to an inclined segment 20, the

latter in turn being secured to inclined brackets or supports X. Thetype-bars normally rest near their free ends upon the elastic sheath 21of a curved support 21, that is connected to brackets 22, which aresecured by screws 23 to extensions or corner-posts 24 of the frame l.Each of the key-levers 2 is provided with an upwardly-extending arm 25,that is provided with a hook-like portion 26, adapted to bear upon thetop of a universal bar 27, that extends transversely across the machineabove the key-levers and is provided at its ends withrearwardly-extending arms 28, which are pivoted at 29 to the sides ofthe frame of the machine. The universal bar 27 bears at its under sideon a forwardly-extending crank-arm 30, projecting` from a rockshaft 3l,that is mounted to turn in bracketarms 32, depending from a frame-likeportion 33.

end of a spring 35, the opposite end of which bears at 36 on a fixed bar37 and tends to restore the rock-shaft to its normal position. Extendingupwardly from the rock-shaft 31 is a dog-rocker 38, which carries theusual or any suitable character of feed-dogs 39 and 40, that cooperatewith an escapement-wheel 4l. The eseapement-wheel is operativelyconnected by the usual pauf'l-and-ratchet mechanism (not shown)contained within the housing 42 to a shaft 43, that extends forwardlyand is supported in suitable bearings 43X,and the forward end of theshaft has a feed-pinion 44 secured thereto. A feed-rack 45 is pivoted byears 45 to swing on a bar46, fixed to the carriage, and meshes with thefeed-pinion 44 and affords a letter-space movement of the carriage whenthe escapement mechanism is actuated by an operation of a finger-key.The carriage comprises end plates 47, that are united by rails orcross-bars 48 49, that are grooved on their lower faces to form racewaysfor the reception of antifriction-balls 50. Bearingrails 5l 52 extendtransversely across the machine and are supported upon lugs l, thatproject inwardly from the machine-frame, (see Fig. 4,) and thebearing-rails 51 and 52 support the frame 33 by connecting-screws 33u.These rails are grooved on their upper faces to form raceways for thereception of the antifrictionballs 50, and thus provide a support forthe carriage, suitable pins or stops being' provided to limit themovement of the carriage and prevent an escape of the antifrictionballsfrom their raceways. Arms 49L and 5l, Fig. 2, are carried, respectively,on the rails 49 and 5l and have rollers 49b pivoted thereto and whichbear upon the rails 48 and 52 and prevent the carriage from being'removed from its supporting-rails.

The cross bar or rail 49 of the carriage has a depending rack 53connected thereto by screws 54, the stems of which pass through slots 55in the rack and into threaded openings in the rail to permit a relativelongitu- This rock-shaft is connected at 34 to one dinalA movement ofthe rack under certain conditions which will hereinafter be explained.Thisrack 53 meshes with a gear 56 that is secured to a shaft 57,extending fore and aft and centrally of the machine and is supported inbearings in the central bracket 2O and in a bracket 57 X, secured to thelower side of the frame 33 bythe screws 33X, which unite the frame tothe cross-supporting rails. The forward end of the shaft 57 (see Fig. 2)has a gear-wheel 58 secured thereto, the gears 56 and 58 being of thesame size. The gear 58 meshes with a rack 59, (see Figs. 2 and 3,) thatcarries a scale 60 on the front face thereof, which scale corres pondsto the letter-spacing of the paper-carriage in its movement from one endto the other of the machine. The rear face of the rack 59 has securedthereto a rail 6l, which extends throughout the length of the rack andis provided on its upper and lower faces with pins 61X near the endsthereof (see Figs. 9 and l0) to limit its movement and with raceways 62for cooperation with antifriction-balls 63. This rail is adapted to bereceived in a channeliron 64, that is secured to the frame of themachine and is provided with oppositely-disposed raceways forcooperation with the antifriction-balls 63, thus forming a support forthe rack 59 and the parts connected thereto, so that these parts are inthe nature of an auxiliary carriage which travels with thepaper-carriage. Pins 64 (see Fig. 9) are situated in the ends of theracewavs in the channel-iron and cooperate with the pins 61 to limit themovement of the auxiliary carriage and prevent the balls 63 fromescaping from their raceways. From an examination of Fig. l it will beobserved that the rack 59 has secured thereto near each end by screws 65a finger-piece 66, by means of which the auxiliary carriage may be movedfrom left to right, at the same time moving` the paper-carriage in thesame direction and to a like extent through the intermediategear-and-raek connection. The upper edge of the rack-bar 59 is providedwith teeth 67, and an additional bar 68 is secured to the rear sidethereof. This additional bar 68 is likewise provided with teeth, whichregister with and constitute parts of the teeth 67, whereas the rearface of the bar is provided with vertically-disposed teeth 67, and theteeth 67 and *67L are adapted to receive the inverted-U- shapedcolumn-stops 69 between them, thus affording means for adjustablyretaining the column-stops on the rack-bar 59. Extending upwardly fromthe channel-iron 64 and to the rear side thereof are brackets 70, theupper ends of which are apertured to receive and constitute bearings fora shaft 7l. This shaft has mounted to vibrate thereon a series of nestedU-shaped denominational key-levers 72, (see Fig. 1,) the key-leversbeing arranged in two series, one series to each side of the cen- IOOter of the machine. Suitable spacing sleeves and washers 78 areinterposed between the arms of these levers to maintain them spacedapart and prevent them from moving longitudinally on theshaft 71. EachU-shaped lever has formed integral therewith a fingerkey 74, whichprojects upwardly and then forwardly therefrom, as shown in Fig. 2. Thearrangement of these finger -keys is such that any U-shaped key-levermay be depressed without depressing' the remaining levers of the nestedseries. rlhe rearwardly-extending centrally-located arms 75 of thedenominational key-levers are situated at letter-space distances apartand are each provided with a projection 76, (see Fig. 2.) that extendsdownwardly therefrom and constitutes a denominational stop thatcoperates with the column stop or stops carried by the so-calledauxiliary carriage when the corresponding denominational keys aredepressed. The centrally-located rearwardly-extending arms 75 of thedenominational key-levers each extends to the rear of the shaft 71,where it forms a finger 77, that cooperates with what may be termed auniversal bar 78 for the tabulating mechanism. rIhis bar 78 is connectedat its ends to a frame (see Fig. 12) vthat is made up of end plates 79,which are united by a cross-bar 8O as well as by the bar 78. The frameis secured to a rod or rock-shaft 8l, which is supported and turns inbearings in the lixed supports 20X, which are situated intermediate ofthe ends of said rod 81. One of the end plates 79 is provided with arearwardly-directed arm 82, that is slotted near its rear end at 83 forthe reception of a pin 84, projecting laterally from an arm 85, that isconnected to a rock-shaft 86, which is adapted to turn in bearings 87,carried by a fixed support 33 and one of the lugs 1n. (See Fig. 4.) Oneend of this rock shaft carries a crank-arm 88, that extends upwardly andis provided with an angular forwardly-directed terminal portion 89,which from an examina` tion of Figs. 2 and l2 it will be seen bears uponthe rear face of the feed-rack 45, intermediate of the teeth at thepivotal center thereof. From the foregoing description it will beunderstood that the so-called "auxiliary carriag'e is adapted undernormal conditions to move with the paper-carriage ormain carriage in themovement of the latter from end to end of the machine, so that thetension of the spring-drum 90, (see Fig. 4,) which is connected by aband '.91 with the paper-car riage, is exerted during the feed movementthereof to propel the auxiliary carriage in the same direction throughthe intermediate racks and gears 53, 56, 58, and 59. It will also beunderstood that each of the denominational keys 74 has a correspondingstop 76 thereon and that these stops are situated at letterspacedistances apart transversely and centrally of the machine and that thestop for the key shown provided with a decimal-point is that which isthe farthest toward the left, (see Fig. 1,) whereas the denominationalkey marker 1M for millions carries the de nominational stop which islocated farthest toward the right-hand side of the machine. A depressionof any of the tabulating or denominational keys 74 will cause thestop-carried thereby to be projected into the path of a column-stop 69on the auxiliary carriage.

The same movement of the denominational key will cause the so-calleduniversal bar 78 to be moved toward the rear through the finger 77,connected to the denominational key-lever. This rearward movement of thebar 78 around its rock-shaft 81 as a center will cause the rear end ofthe arm 82 to be depressed, thus moving the forward end of the arm `85down and vibrating the arm 88 forwardly, which movement is eifective toturn the feed-rack 45 on its rod 46, moving the lower edge thereofforwardly to disengage it from the feed-pinion. The carriage thus beingfreed from its escapement mechanism may be propelled by its spring-drumfrom right to left until the tabulating-stop 69 reaches the stop 76 onthe depressed denominational key-lever, when the auxiliary carriage andthe main carriage as well will be arrested at the proper denominationalposie tion. When pressure on the depressed denominational key isreleased, it will be restored to its normal position by a leaf-spring92, (see Fig. 9,) which is secured at one end by a screw 93 to thechannel-iron 64. The

' upper or free end of the leaf-spring' projects into a recess 94, thatis formed in the hub-like portion of that arm of each U-shapeddenominational key-lever which is not provided with arearwardly-extending finger 7 7-that is to say, the outermost arm ofeach lever. The movement of the key-lever back to the normal position islimited byashoulder 95, which is formed by the forward portion of thefinger 77, and is adapted to bear against an abutment 96, secured to thechannel-iron 64. Vhen pressure is released upon the denominationalkey-lever, the projecting finger 77 is carried to the full-line positionshown in Figs. 8 and 9, and the weight of the bar 8() will restore thearms 82, 85, and 88 and the parts connected thereto to the normalpositions, and the feed-rack45 will be restored to its normal positionin engagement with the feedpinion 44 by a spring 97, Fig. 5, which isconnected at one end, 98, to a hand-actuated arm 99, that is rigidlysecured by a set-screw to a laterally-projecting sleeve 98X, thatextends from one of the ears 45X, which pivotally connect the rack tothe relatively xed bar 46. rlhe bar 46 is fixed against rotation by anangular studv 46u, which is seated within a corresponding opening in theend of a screw 46h, that takes in a threaded opening in an end plate 47of the carriage. The opposite end of the spring 97 is secured to anadjustable sleeve 100, that is cari'ied by the rod 46 and is securedthei'eto by a set-screw 101.

The lixed bar 6, secured to the frame, has a pointer 102 securedthci'eto by a screw 103, and this pointer pi'ojects upwardly from thebar and cooperates with the scale on the auxiliary carriage, asindicated in Fig. 3, and constitutes, with said scale, means forindicating' the position of the paper-carriage i'elatively to theprinting-center.

A depending bracket-arm 104 is secured to the i'ail 61. (See Figs. 2 and3.) This bracket has pivoted thereto at 105 a carriage-release lever106, that has a general horizontal disposition and is provided at itsleft-hand end with a linger-piece 107, by means of which it may bedepressed, the depression of the lever being' limited by a bracket 108,that is secured to and projects down from the lett-hand lingerpiece 66on the auxiliary carriag'e. The inwardly-projecting end ol: the lever106 is pi'ovided with a rearwardly-extending pin 109, which projectsunder a cross bar or rail 80 at all times during the movement oi theauxiliary carriage from end to end of the machine. The depression of thelinger-piece 107 is effective to raise the opposite end of the lever106, thus elevating' the cross-bar 80, which results in depressing thearms 82 and 85, thereby rocking the upper end oi' the arm 88 forwardlyand etfecting a disengagement of the feedrack from its pinion 44. ltwill thus be seen that liaiid-opei'ated carriagc-i'eleasing means areprovided on the auxiliary carriage, by means of which the carriages canbe released at will, and that at the same time the same hand of theoperator which aliiects the release may control the movement of thepaper-carriage throug'h the finger-piece 66 on the auxiliary carriage.In other words, one finger can be employed to depress the finger-piece107 to release the paper-carriage, and a linger on the same hand maygi'asp the left-hand lingerpiece 66 of the auxiliary carriage, thuscontrolling its movement, and consequently the movement of thepaper-carriage.

Upon reference to Fig'. 2 it will be seen that a rounded head. 110 ofthe pin 111 is norn? ally pressed ag'ainst the forward face of thefeed-rack by an expansion-spring 112, which bears at one end against thehead and at its opposite end against the i'ail 49. This pin 111 isseated and moves end wise in an apertui'e in the rail 49, through whichit extends, and when the lower edge of the rack 45 swings forward itwill force the pin against the tension ot its spring, and the forwardend of the pin will be projected through an opening' 113 (see Fig. 11)in the rack 53, thus locking' the rack against longitudinal movementfrom left to i'ight it will cause the paper-carwitli relation to therail 49, so that during the disposition oi' the parts above described,which is the one they normally assume, the

1)aper-carriage and rack 53 move in unison in order that when atabulating-key is depressed and the feed-rack is released the paper andauxiliary carriages will travel together, and when the latter isarrested by a denominational stop the paper-carriage will be arrested ina corresponding position and no independent movement of the twocarriages can take place.v Wfheii the tabulating-key is released,however, the feed-rack is permitted to swing down to the normal positionand the lockingpin 111 is automatically withdrawn from the aperture inthe rack 53.

Extending upwardly from the rack 53 (see Fig's. 2 and 11) is an arm11.4, which is secured at 115 to the 'front face or' the i'ack and isadapted to project into the path of a laterally-extending arm 116, thatis secured toa i'od 117, which is carried by the carriage and moveslongitudinally with relation thereto. The right-hand end portion of therod 117, Fig. 11, is grooved longitudinally at 118 and receives aprojection or pin 118x, Fig. 4, that extends through a relatively lixedportion of the platen-frame that constitutes one of the supports 117"for said rod, and so prevents the rod 117 from turning. Adjustablysecured to the rod by a set-screw 119, Fig. 11, is alaterally-projecting piece 120, which is grooved at 121 for thereception ot' a crankpin 122, that extends downwardly from a crank-arm123, connected to a rock-shaft 124, seated and adapted to turn in aportion 125 of the platen-frame. rlhe bent arm 126, connected to thisrock-shaft, is seated in a slot 127 oiu a vibratory piece orline-spacing pawlcarrier 128, that is pivoted ona sleeve 129, whichsurrounds the platen-shaft 129X near one end thereof. The upper end ofthis part 128 has a line spacing pawl 130 pivoted thereto on a pin 131,that extends to the right of the carrier 128 ior purposes which willhereinafter appear, and the pawl is maintained undei' tension of aspring 132. The nose ot.' this pawl 130 when in the normal position ismaintained by its spring against a shield 133, that is cai'i'icd by aliiie-spaceregulating device 134, provided with a lingerpiece or handle135, by which it may be moved around the sleeve 129, which surrounds theshaft 129 of the platen 136. rlhe adjustment of the device 132 permitsthe pawl 130 to slip oli' the shield 133 and engage the teeth of theline-spacing ratchet-wheel 137 sooner or later dui'ing the throw oit'the pawl, and thus determines the extent of line-spacing movement o1 theplaten.

From the 'foregoing description it will be understood that when thelocking-pin 111 is normall y released from the rack 53 and the auxiliarycarriage is moved by a linger-piece 66 riage to move in a like directionuntil ai'rested by its right-hand or margin stop, (the teeth oi IOO IOS

IIO

the rack-feed at this time being moved over the loose-feed dog.) Thenthe paper-carriage has been arrested in the manner stated, the auxiliarycarriage may receive a slight further independent movement toward theright by reason of the pin-and-slot connection 54 55 between the rack 53and the carriagerail 49, which independent movement results in the rack53 being carried to the right independently of the paper-carriage, andthe abutment 114 on the rack 53 will contact with the finger orprojection 116, causing a longitudinal movement of the rod 117 towardthe right. This movement is effective to rock the shaft 124, thusvibrating the carrier 128 and effecting an automatic line-space movementof the platen throug'h the pawl 130 and the coperating ratchet-wheel137, the rearward vibration of the pawl being limited by a relativelylixed stud 130x. This movement of the auxiliary carriage carries theleft-hand end of the scale past the pointer 102; but as soon as theoperator releases the finger-piece 66 the spring 138 will be eective torestore the rod 117, the rack 53, auxiliary carriage, andv intermediategears to their normal positions relatively to the paper-carriage, andthe proper point onthe scale 60 will be brought into register with itspointer 102.

It will be understood that under certain conditions it may not benecessary to move the carriages to the extreme right in order to effectan automatic line-spacing movement of the platen. Thus if the tension ofthe papercarriage spring and the spring 138 be so proportioned that thetension of the spring 138 is less than that of the carriage-spring theautomatic line-spacing' movement can be effected at the initial part ofthe backward movement of the carriages. Then, again, a quick sharpreturn movement applied to the auxiliary carriage will effect theautomatic line-spacing before the carriages are moved to the extremeright. It will likewise be observed that the spring 138, interposed, asit is, between the paper-carriage and the rack 53, will take up theshock due to the rapid movement of the carriage from left to rightwhenever the carriage is moved to the right through the auxiliarycarriage. 1

The platen 136 through its platen-frame is mounted upon links 139, whichare pivoted at 140 to the carriage and at 141 to the platenframe. Thelower set of these links carry or in part constitute the supports 117,in which the bar 117 moves longitudinally and the disposition andconnection of the links 139 with the carriage and platen-frame is suchthat the platen-frame will be moved in an inclined plane when thecrank-arm 141x, Fig. 2, is depressed by suitable means (not shown) toshift the platen transversely for upper and lower case printing, and theplaten-frame is limited in this movement by fixed studs 47X, that pro-K129X, but fixed to the platen-frame.

movement to the platen the machine is provided With a hand-operatedline-spacing device at the right hand of the paper-carriage, so that thespacing movement of the platen may be elfected at any time-and is notdependent upon the movement of the carriage toward the right by theauxiliary carriage. This hand-operated .line-spacing device consists ofa vibratory piece 142, which is provided with an upwardly-extendedfinger-piece 143, by which it may be moved around the platensleeve 129,on which itl is mounted, the piece being restored to the normal positionby a spring 144, Fig. 4. The piece 142 stands in front and is adapted tovibrate in the path of the extensions on the pin 131, Fig. 11, of thepawl-carrier. The effect, therefore, of moving the finger-piece 143toward the rear of the machine is to vibrate the line-spacing-pawlcarrier 128 lto be moved toward the rear of the machine, thus eifectinga line-spacing movement of the platen. During this movement of therock-shaft by means of the fingerpiece 143 the rod 117 will be movedtoward the right by reason of the intermediate connections between thecarrier and said rod. This movement, however, will be an idle one andwill in no way affect the rack 53.

In addition to the paper-carriage-release key that is carried by theauxiliary carriage l have provided a hand-operated release device on theleft-hand end of the paper-carriage and `which consists of thelinger-piece 145, Figs. 6 and 7, that is mounted to turn on a sleeve146, seated loosely on the platen-shaft The finger-piece has arearwardly-extending portion 147 connected thereto and to which ispivoted at 148 a plunger or rod 149, that is guided in an aperture inthe paper-apron 150 and is adapted to bear at its lower end against thearm 99, which, as hereinbefore described, is secured to one of the earswhich connect the feed-rack 45 to the rod 46 and projects upwardlytherefrom. (See Fig. 5.) A spacingwasher 151 is secured to the sleeve146 by a set-screw 151 and is recessed at 152 for-.the reception of apin153, vcarried by the part 145, and which limits the movement of thefingerpiece and the parts connected thereto. Wvhen the linger-piece ismoved from the position shown in Fig. 6 to that indicated in Fig. 7, aplunger 149 will be forced down against the arm 99, thus swinging thefeed-rack out of engagement with the feed-pinion 44, and the carriagemay be moved in either direction. The finger-piece is restored to thenormal position by a spring 145x. (See Fig. 5.)

IIO

Cooperating with the platen are paper-feed rollers 153, Figs. 6 and' 7,that are mounted upon a shalt 154, which extends throughout the lengthor' the platen and beyond the ends thereof. This shaft 154 is connectedat its ends to links or toggle-levers 155, which are pivoted at 156 toan arm 157 that is connected to a linger-piece 158 and is mounted toturn on the sleeve 146. The shaft 154 is likewise connected to links159, that are pivoted tothe relatively iixed rod 160, that is carried bythe platen-frame and constitutes a support and pivot for the links offeed-rollers 153 and the paper -table 160 as well. Bowed springs 161 areeach connected to the rod 160 byscrews 162, the stems of which passthrough openings in ears 161X of the spring, as indicated in dottedlines in Fig. 5, and take in threaded openings in the rod 160. The stemof a screw 161L passes through an opening in each spring 161 and isreceived within a threaded opening' in the rod 160, whereas the head.thereoiI bears against the outer or rear portion of the spring', therebyconstituting means Yl'or adjusting the tension of the spring. The loweror free ends of the springs 161 bear against the shaft 154 and tend tomaintain the feed-rollers in contact with the platen, as indicated inFig. 7. The construction and arrangement of the toggle levers or links157 and 155 is such that they will be brought into alinement or to adead-centered position when the arm 158 is moved to the position shownin Fig. 6, thereby forcing the shaft 154, with its feed-rollers,

away from the platen to the position indicated in said ligure, themovement of the shaft being around the rod 160 as the pivotal center.1When, however, the finger-piece 158 is moved forward, the toggle linksor levers 155 and 157 will be moved from the dead-center position (shownin Fig. 6) to the position indicated in Fig. 7, and the tension of thespring 161 will be effective to press the rollers 153 against theplaten. It will be understood that no means other than these shown anddescribed are necessary to maintain the feedrollers out of contact withthe platen when the parts have been moved to the position indicated inFig. 6, the pressure of the springs 161 at this time being exertedagainst the dead-center of the toggle-levers.'

The paper-carriage is provided with a crossbar 163, (see Figs. 2 and 4,)from which extends an upright bracket-arm 164, that has a gravity stopor trip 165 pivoted thereto at 166. This stop has a depending weightedportion 167, that extends to one side ol.I the pivotal center of thestop and tends to normally maintain the stop against the relativelyfixed pin 168, carried by the bracket 164. Pivoted to what may be termeda top plate 169 of the machine is a rack or stop bar 170. This bar isrecessed or apertured at its ends, as indicated at 171, for thereception ol pins 172, and the construction is suoli thata slightlongitudinal movement may be imparted to the bar as well as a turningmovement on its pivot-pins. Adjustably secured to the rack-bar orstop-rod 17 O is a combined trip or stop 173, which has a cam-like tripportion 174 projecting therefrom in advance or to right of the stop 175.The part 173 is adapted to be adjusted to any suitable point on thestop-bar, which is provided with a scale on its Lipper face thatcorresponds to the carriage-scale in order to facilitate suchadjustment. Depending' from the stop-bar is a pin 176, which is receivedin an opening in the upper bent end of a lever 177, that is pivoted to alixed portion of the machine, as indicated at 178, and is connected atits lower end by a pin-and-slot connection 179 to a bar 180, thatextends transversely across the machine and is supported near its endswithin slots formed in the depending' bracket-arms 181, secured byscrews 182 to lugs 1, that project inwardly from the iframe of themachine. The bar 180is provided with depressions or slots 184 near theends thereof, and when the bar is inthe normal position these slots arebeneath the rearwardly-extending' arms 28 of the universal bar 27 andpermit the depression thereof. Vhen, however, the bar 180 is movedtoward the right in Fig. 4, the slots 184 are moved out of register withthe arms 28 and the full or higher portions of the bar are broughtbeneath the arms, thus preventing a depression thereof. Thislongitudinal movement of the locking'- bar to eii'ect the locking of theuniversal bar is eliected when the carriage brings the stop 165 intocontact with the stop 175 and moves the stop-bar 17() from right to leftand against the tension of a spring 177 X, that restores the parts totheir normal positions, with the stopbar 17 O at the limit of itsmovement toward the right. This movement of the stop-bar from right toleft results in a corresj'ionding movement of the upper en d of thelever 177, with the movement of the lower end of said lever in anopposite direction, thereby effecting a locking movement of the bar 180.Then the locking-bar 180 is in the locking position, a depression of theuniversal bar will be prevented, and it follows that at this time a de-'.pression of the finger-keyswill likewise be prevented. Then thecarriage is moved away from the stop 175 and toward the right, thespring 177x, which cooperates with the lever 177, will move it, togetherwith the parts connected therewith, to the normal position, and thelockingbar will be automatically moved to a position where the universalbar is free to be depressed. A margin-stop release key-lever 185 ispivoted in the machine in a similar manner to the key-levers of thetype-actions and is provided with a linger-key that extends to thekeyboard of the machine. This key-lever is pivoted to anupwardly-extending link 186, as indicated at 187, the upper end of thelink being pivoted at 188 to an IOO IIO

arm 189, that is riveted at'190 to a pin or crankarm at 191, thatprojects downwardly and forwardly from the lower side of the stop-bar170. Should the operator desire to write one or more characters afterthe line-lock mechanism has been locked in order to complete a word orsentence or to insert a hyphen, it is merely necessary to depress thekey-lever 185, thus rocking the bar 17() on its pivotal center, and thismovement is effective to move the stop 175 out of the path of andcontact with the stop 165. rIhe spring 177 will then move the bar 170from left to right and a releasing movement of the universal bar will beeffected. It will be understood that the trip 174: on the part 173 isemployed to turn the bar 170 and effect a sounding ot' an alarm by theusual means (not shown) before the line-lock mechanism is actuated toprevent a depression of the finger-keys.
